SPECIFICATION forming part of Letters Patent No. 437,574, datedSeptember 30, 1890.

l Application led December 12, 1889. Serial No. 333,462. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, LEIGHLIN CONROY, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Magazine Fire-Arms, of which thefollowing is a specification.

My invention relates to certain ne7 and useful improvements in magazinefire-arms, known as bolt-guns, or arms wherein a reciprocatingbreech-block provided with an extractor and firing-piu is used, and Ihave pointed out said improvements in the following specification andclaims and illustrated the same in the accompanying drawings, in which-Figure l represents a longitudinal sect-ion, showing the rear portion ofthe gun with the parts in position after a cartridge has been fired, theempty shell being still in the barrel. Fig. 2 is an addition to Fig. 1,showing the front end of the gun when the feed-slide is in the forwardposition. Fig. 3 is a transverse section in the plane Fig. l. Fig. 4 isa longitudinal section showing the bolt partially drawn back.V Fig. 5 isa transverse section in the'plane x', Fig. 4. Fig. 6 is a plan or top-view of the feed-slide and follower detached. Fig. 7 is a similar viewto Fig. 4 when the bolt has been drawn back completely, on a largerscale than the previous figures. Fig. 8 is a similar view to Fig. 2 whenthe feedslide is drawn back. Fig. 9 is a transverse Section inthe planey y, Fig. 8. Fig. 10 is a horizontal section in the plane z z, Fig. 7.Fig. 11 is a vertical section in the plane z z', Fig. 10, the bolthaving been removed to expose the parts below. Fig. 12 is a transversesection in the plane z2 z2, Fig. 10. Fig. 13 is a longitudinal centralsection of the rear portion of the gun when the same is adjusted for asingle-loader. Fig. 14 is a transverse section in the plane x2 m2, Fig.13. Fig. 15 is a plan or top view of the carrier detached. Fig.`16 is atransverse section in the plane 0632123, Fig. 15. Fig. 17 is a plan viewof the locking-sleeve carrried by thebolt. Fig. 1S is a detachedelevation of the feed-pawl and the stop-pawl.

In the drawings, the letter A designates the barrel, which is secured inthe receiver A.

B is t-he bolt, and C is the magazine, which is situated beneath thebarrel, and into which fresh cartridges may be introduced through thebreech of the gun when the boltis drawn back.

The cartridges are fed toward the breech by means of a follower D, whichis actuated by the feedslide E, as will be presently eX- plained. Thefollower' is composed of two heads a a, which are connected by twoplates b b. plates are situated two pawls c d, which swing on a commonpivot co, the pawl c being the feed-pawl and the pawl d the stop-pawl.From the hub of the feed-pawl c extends a tail c into a groove c2 in thebore C', to which the magazine C is secured.

In the bottom part of themagazine is firmly secured a rack-bar d', whichis provided with ratchet-teeth cl2, Fig. 6, the distance between whichis equal to the length of the cartridges, and which are in position forengagement with the stop-pawl d.

The feed-slide E extends on the side of the fixed rack-bar d andisprovided with ratchetteeth c3, the distance between which is equal tothat between the teeth d2 of the rack-bar d', and which are in positionfor engagement with the feed-pawl c.

The stop-pawl d is provided with a slot d3, Figs. 8 and 18, and thefeed-pawl c is provided with a pin d4, which engages the slot d3, sothat when this feed-pawl is raised a sufficient distance the stop-pawl:is thrown out of engagement with the rack-bar d', and when thefeed-pawl is depressed it carries the stop-pawl along. The pin d4,however, has sufficient play in the slot d3, so that when the feed-bar Eis moved forward and the feed-pawl is raised thereby the stop-pawl isnot thrown outot engagement with the stationary rack-bar d', and thestop-pawl will only be thrown out of engagement with the stationaryrack-bar when the magazine has been exhausted, as will be presentlyexplained. Both pawls are exposed to the action of spring-actuated stopsd5 d, respectively, which extend into notches in the hubs of the pawlsand serve to retain said pawls with a force commensurate to theirsprings when the pawls 'are down and when they are up.,

The feed-slide E receives a reciprocating motion by means of a dog F,pivoted to the (See Figs. 6 and 9.) Between these IOO 2 Y' 4mm upon thecarrier L, while the projection f of the dog F strikes the ridge G,sovthat the said dog is thrown out of gear with the feed-slide E, Figs.4 and 7 The carrierL is trough-shaped, Figs. and 16, and it swings onpivots l. When the bolt B is moved from the position shown in Fig. 4 tothat shown in Fig. 7, the

projection H strikes the tail of the carrier, and

the front portion of said carrier, which carries a cartridge, is raisedto the position shown in Fig. 7,l and the cartridge is ready to bepushed into the barrel by the subsequent forward movement of the bolt.

The carrierL is locked in its raised position by a spring-catch I, Fig.7, which is situated beneath the barrel, and when the bolt is movedforward, so as to close the breech, this spring-catch is pushed back tothe position shown in Fig. 1, and the carrier L being released returnsto its original position, while the follower D remains stationary, beingheld in position by the stop-pawl d. As the bolt is moved forward, thefeed-slide is pushed forward in the magazine, and when the bolt is againdrawn back the next cartridge is 4pushed upon the carrier. When themagazine has been exhausted, the tail c of the feedpawl strikes theshoulder c7 at the inner end ot the groove c2, and both pawls c d areraised and retained in this position by the springstops d5 d6, Fig.4,-so that by bringing the gun in an inclined position the follower Dcan be made to slide tothe forward end of the magazine and freshcartridges can be introduced. When the follower reaches the forward endof the magazine, the tail c strikes the shoulder ce, Fig. 2, and bothpawls are returned to their workin g positions. A stop e9 limits thebackward movement of the tail c.

When the feed-slide Eis in its forward position, Fig. 1,` the dog F,which engages the recess e0 in the rear portion of the feed-slide, is inposition to be thrown out of engagement with the feed-slide bytheact-ion of a lever J, which has its fulcrum onapivot j, and the tail endof which engages a recess j@ in the hub of a finger-lever K, which hasits fulcrum on a lpivot k. If the finger-lever is moved in the reversedirection indicated by the arrow shown near it in Fig. 1, the lever Jthrows the dog F out of engagement with the feed-slide, and the tail endof the lever K acts upon the carrier vL 'and moves the same up into thebreech and retains it in the position which said carrier occupies inFig. 13. The bolt B can now be moved backward and forward withoutactuating the feed-slide, andthe gun can be used as a single-loader.

On the rear end of the bolt Bis fitted a sleeve M, from which extends ahandle N, and which is retained in position by a screw-cap O. (See Figs.1 and 4.) On the body of the sleeve M is cut a screw-thread, portions ofwhich are cut away, so as to form a series of threaded segments m m2 m4,which alternate with the plain segments fm m3 m5, Figs. 3, 5, and 17. Onthe rear end of the receiver A is cut a screw-thread to engage thescrew-thread on the sleeve M, and this screw-thread in the receiver isformed into plain segments and threaded segments corresponding to thesegments m m fmz'mmf m5 on the sleeve, but disposed in such a mannerthat when the handle Q N of the sleeve occupies a vertical position thethreaded segments m m2 m4 stand oppositethe plain segments in thereceiver, and if the bolt B is pushed forward to the position shown inFig. l the threaded segments m m2 m4 of the sleeve enter thecorresponding plain segments in the receiver. Vhen the handle N is thenturned to the position shown in Fig. 1, the threaded segments m m2 m4 ofthe sleeve lengage the adjoining threaded segments in the receiver, andthe front end of the bolt is firmly presssed up against the rear end ofthe barrel and held there while the gun is fired. By these means thebolt can be firmly locked without turning the same, and when the bolt islocked the handle N does not obstruct the sight.

On the bolt are secured the extractors P. (See Figs. 7, 10, 1l, and 12.)They are fitted into recesses p in the body of the bolt and held inposition by scrcwsp, which extend through slots p2 in the Shanks of theextractors, so that said extractors can slide a short distance in thedirection of their length When the carrier L, together with thecartridge, is raised to the position shown in Fig. 7, the rim of thecartridge is forced between the extractor, (see Fig. 10,) so that thehooks p3 of said cartridges are in front of the rim of the cartridge. Ifthe bolt is now pushed forward so as to close the breech, the hooks p3of the extractors enter the recesses p4 in the rear end of the barrel,Fig. 7, and when the gun has been fired and the bolt is moved back thehooks p3 carry the empty shell of the cartridge back into the breech,whence it can be readily removed.

From this description it will be seen that the rims of the cartridgesare thrown in engagement with the extractors by thev action of thecarrier, and it is onlynecessary to move the extractors far enough outbeyond the end of the bolt, Figs. 7 and 10, so that if a cartridge israised up by the carrier the rim of said cartridge will occupy aposition behind the noses of the extractors. Vhen the bolt is pushedforward, the cartridge is driven into the rear end of the barrel and theextractors enter the recesses p4, and as their front ends strike theends of these recesses they (the ex- ICO IIO

tractors) slide back, and the cartridge is retained in close contactwith the front of the bolt, Fig. 1. The extractors do not spring overthe rims of the cartridges, and the recesses p4 are'made just deepenough to be filled up completely by the front ends of the extractors,leaving no ventage when the cartridge is iired. If the bolt is movedback the extractors remain stationary for a short time, and by the timethe screws p strike the rear ends of the slots p2, Fig. 10, the bolthasacquired sufficient momentum to cause the eX- tractors to throw thecartridge out with the required velocity.

What I claim as new, and desire to secure by Letters Patent, is- Y 1. Ina magazine ire-arm,the combination, with the barrel A, the receiver A',and the bolt B, of the magazine C beneath the barrel, the feed-slide E,provided with ratchet-teeth, the rack-bar d', fixed in the magazine, thefollower D, the pawls c d, mounted in the follower, and the dog F,carried by the bolt and constructed to engage the feed-slide,substantially as described.

2. The combination, with the barrel A, the

receiver A', the bolt B, and the magazine C, of the feed-slide E, thedogF, carried by the bolt and constructed to engage the feed-slide, theprojection G to throw the dog F out of gear with the feed-slide, thecarrier L, and the projection Il on the bolt for actuating the carrier,substantially as described.

3. The combination, with the barrel A, the receiver A the bolt B, andthe magazine C, of the carrier L, the projection H on the bolt, and thelatch I in the front part of the receiver, substantially as described.

4. The combination, with the barrel A, the receiver A', the bolt B, andthe magazine C, of the feed-slide E, the dog F, carried by the bolt andconstructed to engage the feed-slide, the leverJ,for throwing the dog Fout of gear with the feed-slide, the iinger-lever K, and the carrier L,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubseribin g witnesses.
